Background: Transrectal ultrasound-guided prostate biopsy (TRBx) or transperineal Bx (TPBx) are considered alternative approaches for the diagnosis of prostate cancer (PCa). However, urinary tract infection (UTI) or other complications could be more frequent in the TRBx approach. Objective: To determine the complication rate following different antimicrobial prophylaxis (AMP; fosfomycin trometamol [FT] vs beta-lactame or fluorochinolones [FQ]) in patients undergoing TRBx or TPBx. Design, setting, and participants: The analyses were based on prospectivelycollected data of a cohort of patients who underwent TRBx or TPBx for elevated prostate-specific antigen (PSA; >= 4 ng/ml) or clinical suspicion of PCa, between September 2016 and March 2017. Patients received a single dose of 3 g oral FT (group A) or, alternatively, FQ or beta-lactame (group B). Intervention:TRBx versus TPBx. Outcome measurements and statistical analysis: Adjustment variables consisted of age, PSA, biopsy technique (TPBx vs TRBx), and antibiotic prophylaxis (FT vs beta-lactame or FQ) using 1:1 propensity-score matching. Overall, 526 patients were considered, of whom 258 received FT (group A) and the other 258 received beta-lactame or FQ (group B). Results and limitations: Overall complications occurred in 390 (75.58%) and major complications in 67/516 (12.98%). Lower prevalence of UTIs was detected in group A (34.1%) compared with that in group B (43.4%; p = 0.03), while similar rates of haematuria (54.7% vs 55.4%), haemospermia (39.5% vs 33.0%), and acute urinary retention (11.6% vs 9.3%) were detected in groups A and B. We found that group B (odds ratio [OR]: 1.54; p = 0.03), I grade haematuria (OR: 6.17; p < 0.01), and II grade haematuria (OR: 5.13; p < 0.01) were significantly associated with increased risk of UTIs. Conclusions: AMP with fluoroquinoles or beta-lactam antibiotics increased the rate of UTIs, when compared with FT, in patients undergoing TRBx or TPBx. The appearance of haematuria or haemospermia is associated with UTIs, suggesting the possibility of tailoring the strategy for prophylaxis in this category of patients. Patient summary: In this study, comparing complications after transrectal ultrasound-guided prostate biopsy versus transperineal biopsy, prophylaxis with fluoroquinoles or beta-lactam antibiotics increased the rate of urinary tract infections when compared with fosfomycin trometamol, regardless of the type of biopsy approach.

In this work, we report three deep-blue emitting cationic iridium complexes Ir1-Ir3 with 2′,6′-difluoro-2,3′-bipyridine cyclometalated ligand and pyrazole-type ancillary ligands. Synthesis, crystal structure, photophysical and electrochemical properties of Ir1-Ir3 are studied in detail. Ir1-Ir3 exhibit efficient phosphorescence emissions at 439, 438 and 437 nm with CIE 1931 coordinates of (0.14, 0.12), (0.14, 0.12) and (0.14, 0.13), and luminescence quantum yields of 0.35, 0.27 and 0.50 in CH2Cl2 solutions, respectively, which are among the highest levels of ever reported cationic iridium(III) complexes emitting deep-blue light. High luminescence quantum yields, excellent color purity and short lifetimes demonstrates the great potential of Ir1-Ir3 for lightemitting electrochemical cells (LECs) and solution-processable organic light-emitting diodes (OLEDs) as efficient blue emitters.

Using TiOⁱPr4 with a pyrazole ligand for one-pot LA polymerization improved catalytic activity compared with using TiOⁱPr4 only. At 60 degrees C, TiOⁱPr4 with ^furPz exhibited a higher catalytic activity (approximately 3-fold) than TiOⁱPr4. At room temperature, TiOⁱPr4 with ^BuPz exhibited a higher catalytic activity (approximately 17-fold) than TiOⁱPr4. High molecular mass PLA (MnGPC = 51 100, and D = 1.10) could be produced by using TiOⁱPr4 with ^furPz in melt polymerization ([TiOⁱPr4] : [^furPz] = 1000 : 1 : 1 at 100 degrees C, 240 min). The crystal structure of ^MePz2Ti2OⁱPr7 revealed the cooperative activation between two Ti atoms during LA polymerization.

A new fumarato bridged Zn(II) coordination polymer viz. catena[mu-fumaratobis(3,5-dimethylpyrazole)zinc(II) trihydrate],{[Zn-2(mu-fum)(2)(Hdmpz)(4)]center dot 3H(2)O}(n) (1) (where, fum = fumarate, Hdmpz = 3,5-dimethylpyrazole) has been synthesized in purely aqueous medium at room temperature. The compound is structurally characterized by single crystal X-ray diffraction, FT-IR, electronic spectroscopy, PXRD and TGA. The zig-zag polymeric chain of 1 self assembles into a 2D supramolecular network via C-H center dot center dot center dot pi, C-H center dot center dot center dot C, N-H-center dot center dot center dot O and C-H center dot center dot center dot O interactions. Particularly relevant in 1, since in addition to the aforementioned non-covalent interactions, the electron rich pi-system of fumarate is involved in energetically significant unconventional pi-pi contacts with the electron poor pi-cloud of Hdmpz, which have been analyzed by DFT calculations and characterized using the non-covalent interaction (NCI) plot index. The strong H-bond agrees well with the MEP analysis since it is established between the H-bond donor involving NH group of Hdmpz and the H-bond acceptor involving O-atom of carboxylate moiety. The compound has been investigated for anticancer activities considering cell cytotoxicity, apoptosis and molecular docking as parameters in Dalton’s lymphoma (DL) malignant cancer cell line and results were compared with cisplatin (reference drug) under the same experimental conditions. Interestingly, negligible cytotoxic effect was observed against normal cells (PBMC) in comparison to the cancer cells (DL). The treatment of the compound caused appearance of apoptotic cells as evident by fluorescence based nuclear morphology study. The in silica study reveals that the compound interacts with the antiapoptotic proteins such as bcl-2, bcl-XL and Mcl-1 which may lead to apoptotic cell death.

Comparison of various organic compounds such as glycols, amines and alkanolamines as organocatalysts in amidation of fatty acid methyl esters with 3-(dimethylamino)-1-propylamine was made for the first time. It was experimentally detected that catalysts containing OH-groups (alcohols, glycols, glycerol and aminoalcohols) influence the reaction rate. Moreover, catalytic effect is depending on the catalysts geometry significantly. 1,5-diols (e. g. diethylene glycol and diethanolamine) were found to accelerate the reaction more than other OH-groups containing additives. It was supposed, that this catalytic effect is caused by specific associative interactions between reactants and 1,5-diols, what was confirmed by quantum mechanics calculations. Catalysts concentration effects on the reaction rate were also investigated.

A transformation of fluxional into configurationally stable axially chiral N-arylpyrroles was achieved with a highly atroposelective electrophilic aromatic substitution catalyzed by a chiral-at-metal rhodium Lewis acid. Specifically, N-arylpyrroles were alkylated with N-acryloyl-1H-pyrazole electrophiles in up to 93 % yield and with up to >99.5 % ee, and follow-up conversions reveal the synthetic utility of this new method. DFT calculations elucidate the origins of the observed excellent atroposelectivity.

The controlled generation of hydrogen sulfide (H2S) under biologically relevant conditions is of paramount importance due to therapeutic interests. Via exploring the reactivity of a structurally characterized phenolate-bridged dinuclear zinc(II)-aqua complex {LZnII(OH2)}(2)(ClO4)(2) (1a) as a hydrolase model, we illustrate in this report that complex 1a readily hydrolyses CS2 in the presence of Et3N to afford H2S. In contrast, penta-coordinated [Zn-II] sites in dinuclear {(LZnII)(2)(mu-X)}(ClO4) complexes (7, X = OAc; 8, X = dimethylpyrazolyl) do not mediate CS2 hydrolysis in the presence of externally added water and Et3N presumably due to the unavailability of a coordination site for water at the [Zn-II] centers. Moreover, [Zn-II]-OH sites present in the isolated tetranuclear zinc(II) complex {(LZnII)(2)(mu-OH)}(2)(ClO4)(2) (4) react with CS2, thereby suggesting that the [Zn-II]-OH site serves as the active nucleophile. Furthermore, mass spectrometric analyses on the reaction mixture consisting of 1a/Et3N and CS2 suggest the involvement of zinc(II)-thiocarbonate (3a) and COS species, thereby providing mechanistic insights into CS2 hydrolysis mediated by the dinuclear [Zn-II] hydrolase model complex 1a.

Electrocatalytic hydrogenation is a particularly attractive approach for converting the most unstable compounds in biogenic feedstocks at ambient conditions without external H-2. Here, we synthesized a variety of carbon-supported transition metal catalysts and characterized their activity for the electrocatalytic hydrogenation of a series of model compounds and pyrolysis bio-oil. Carbonyl compounds, especially aromatic aldehydes, such as furfural and benzaldehyde, are particularly inclined to hydrogenation driven by an applied current. This was verified with pure solutions of the model compounds and with pyrolysis bio-oil, where we achieved stable and steady continuous operation on Pd. When optimal catalyst composition was chosen, the conversion of benzaldehyde shifted from alcohol production (e.g., on Pd and Cu) to dimerization (e.g., on Co, Ni, and Zn). Pd and Cu were shown to offer the best compromise between reaction rates and efficiency although, in general, base metals offer similar conversions but better efficiencies than noble metals. Thus, the present work offers foundational results and guidelines for choosing the optimal metal catalyst and the applied potential for processing organic feedstocks as a function of its composition.
